A certain granola bar has 2 grams of fiber. This is 8% of the recommended daily value. How many grams of fiber are recommended d
xeze [42]
If you formulate the question into a word equation it comes out: 

2 grams fiber = .08   <span>×    DRV
          </span>↑          ↑   ↑     <span>↑</span>      <span>↑
    2 g fiber    is  8%  of   the daily recommended value.

Now solve for DRV to find the daily recommended value:

2 g fiber/.08 = DRV

DRV = 25 g fiber</span>

The perimeter of a playing card is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the playing car
Arlecino [84]

Step-by-step explanation:

We get two equations here. One for the area and one for the perimeter. The area gives us x×y=50. The perimeter, if we have a rectangle, x+y+x+y=30=2x+2y. For this to work we need to make a simple expression for x or y. Let's go with x here. 2x+2y=30 so x=15-y. if we fill that in the other equation we get (15-y)×y=50 (see picture). y=5 or y=10. If we fill in x×5=50 we get x=10 and vice versa. So the dimensions are 5 centimeters by 10 centimeters

Quadrilateral DEFT has vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3). What is the best name for quadrilateral DEFT?
Hoochie [10]

Answer:

parallelogram

Step-by-step explanation:

slope of DE = (4-7) / (-4 - 2) = 1/2

slope of FT = (-3 - -6) / (11-5) = 1/2

DE // FT

slope of EF = (-6 - 4) / (5 - -4) = - 10/9

slope of DT = (-3 - 7) / (11 - 2) = - 10/9

EF // DT
